LUBRIGATING APPARATUS.

Application filed April 25, 1928. Serial N0. 272,722.

This invention relates to lubricating ap paratus, and more particularly to devices of this character for lubricatii'ig the trucks of trolley conveyers and the like, andhas for one of its objects the provision of a lubricator which will be simple in construction, comparatively inexpensive to manufacture and install, and more eliicient in action than those whichhave been hereto-tore proposed.

A further object of the invention is to provide a lubricating device of the class de scribed which will automatically supply lubricant to the journals of a trolley truck whenever such truck passes the apparatus.

With the above and other objects in View, which will appear as the description proceeds, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed, and particularly pointed out in the appended claims.

Referring to the accompanying drawing forming a part of this specification, in which like reference characters designate like parts in all the views I v Figure 1 is a longitudinal sectional view, partly in elevation, of a portion of a trolley conveyer trackway, with a lubrication apparatus constructed in accordance with the present invention applied thereto;

Fig. 2 is a top plan view of the parts shown in Fig. 1; and

Fig. 3 is an enlarged transverse sectional view, taken approximately on the plane indicated by the line 3-3 of Fig. 1.

1n the said drawings the invention has been illustrated as applied to a trolley conveyer having a trackway 5 of the inverted channel type, although as the description proceeds it will be obvious that with minor changes the invention may be adapted to trackways of various cross sections. In the form shown the trackway 5 has a top web 6 and depending side legs 7, the lower portions of which are turned inwardly to provide horizontal ledges 8 upon which the wheels or rollers 9 of the trolley trucks 10 run. The extreme inner ends of the ledges 8 may or may not be turned upwardly as in dicated at 11.

The ledges 8 are provided at one or more points with apertures 12 cut through them, beneath which are secured suitableoil-receiving pans or receptacles 13 from which lead pipes or conduits 14 connecting the said receptacles with the wells 15 as clearly shown in 3. Suitable lubricant containers 16 having discharge nozzles or spouts 17 are removably positioned in the said wells 15 and erve to maintain a constant supply of lubricant in the pans or receptacles 13 as will be readily understood. '1 I I A pair of arms or levers 18 are pivotally secured as at 19 to the trackway 5 adjacent the top portion thereof, as clearly shown in Figs. 1 and 3, which'arms or levers are pro vided with the downwardly inclined portions 20 which extend through the slots or apertures 12, cut in the flanges 8 ofthe trackway; the extreme end portions 21015 the arms or levers 18 beyond the inclined portions 20 normally extend in a horizontal position within the pans or receptacles 13, -as will be readily understood from Fig. 1. v i

The wheels 9 of the trolley' trucks 10 are usually journalled upon shafts such as 23 carried by hangers 24: and it is the function of the present invention to lubricate these wheel journals. The manner in which such lubrication is automatically accomplished will bereadily apparent from Fig. 1 wherein a trolley truck is shown in full and broken lines in two dilferent positions as it travels along the trackway 5. That is to say, as the truck moves from the full-line position to the broken-line, position it will be obvious that portions otthe wheels 9 engage the inclined portions 20 of the arms 18, which arms, being pivoted as at 19, will be caused to rise to the broken-line position shown in Fig. 1, whereby the extreme horizontal end portions 21 of the said arms are lifted up through the slots or apertures 12, carrying with them some of the lubricant contained in the pans or receptacles 13, which lubricant will be deposited upon the hubs of the wheels 9 and will, of course, find its way to the journals of the said wheels, thereby eltectively lubricating such journals. As soon as the trolley truck passes the extreme end of the horizontal portions 21, the arms 18 will, of course, drop to their tull-line positions shown in Fig. 1, so that the end portions 21 will receive a fresh supply of oil or other lubricant for the next truck. The web 6 of the trackWa-y 5 is of course cut away as indicated at to accommodate the arms 18 in their upward movements.

While one form of the invention has been illustrated and described it is obvious that those skilled in the art may vary the details of construction as well as the precise arrangeceptacle mounted adjacent said trackivay;

and means normally 'positioned'in said receptacle, and in the path of a trolley truck, engageable by said truck to transfer lubricantvfrom-said receptacleto the wheel bean ings of said truck.

2. In a lubricating device for trolley conveyers and the like the combination with a trolley trackway of a lubricant-receiving receptacle carried by said traclrway; and an arm pivotally carried by said trackway, having a portion normally entering said receptacle, s aid portion being engageable by a trolley truck to transfer lubricant from said receptacle to the Wheel'bearings of said truck.

3. In a lubricating device for trolley conveyers and the like, the combination With a trolley trackway having an aperture, of :1

lubricant-receiving receptacle secured to said trackWa-y beneathsaid aperture; and an arm pivot-ally carried by said trackway, having a portion norn' ally projectin through said aperture into said receptacle, said portion being adapted to be Withdrawn through said aperture to transfer lubricant from said receptacle to a trolley truck.

4:. In a lubricating device for trolley conveyers and the like, the combination with a trolley trackvvay having an aperture, of a lubricantaeceiving receptacle secured to said trackivay beneath said aperture; means for supplying lubricant .to said receptacle; and

an arm pivotally carried by said traclrway,

'having an inclined portion passing through said aperture and a horizontal portion normally positioned in said receptacle, said inclined portion normally lying in the path 01 a trolley truck and being engage able thereby to lift said horizontal portion through said aperture, to transfer lubricant from said receptacle to said truck.

In testimony whereof We affix oursignai tures.
